Abstract
Recent neutron magnetic scattering experiments from single crystals of both undoped and doped cuprous "214" oxides are reviewed. The magnetic properties in the undoped crystals are essentially interpreted by the quantum two-dimensional Heisenberg antiferromagnetic model. The three-dimensional long-range order occurs because of small but finite interplanar magnetic coupling plus various anisotropies. The doping of charge modifies the spin correlations significantly as well as the spin fluctuations, which suggests close correlations between the charge and spin degrees of freedom.

Funding
The present paper is based upon a collaborative project between Brookhaven National Laboratory, Massachusetts Institute of Technology and Tohoku University, with the tight cooperation of the crystal growing groups of IMS of Tohoku University, NTT, and the Inorganic Material Synthesis Facility at Yamanashi University. The authors are greatly indebted to all their collaborators, but specifically to Y. Hidaka, S. Hosoya, and H. Kojima. The neutron scattering experiments have been performed with the support of the US-Japan and UK-Japan neutron scattering collaboration programs. The work at Tohoku University is also supported by a Grant in Aid for the Scientific Research. Both are sponsored by the Japanese Ministry of Education, Science and Culture.
